In a cross between two black guinea pigs what is the probability that an offspring will be black?
So I took the worksheet and found that in Punnett Square A (if you have the same worksheet) It has the pairs BB, Bb, Bb, and bb. B= black and b= white. The probablility of a black guinea pig is likely and white is unlikely since there is only 1 trait with 2 recessive alleles.
What is the probability of getting a diamond and a black 7?
The probability of getting a diamond and a black seven is zero. Diamonds are red.
What is the probability of drawing a black card and a 7?
To calculate the probability of drawing a black card and a 7 from a standard deck of 52 cards, we first determine the total number of black cards and the number of 7s in the deck. There are 26 black cards (13 spades and 13 clubs) and 4 sevens in the deck. The probability of drawing a black card and a 7 is calculated by multiplying the probability of drawing a black card (26/52) by the probability of drawing a 7 (4/52), resulting in a probability of (26/52) * (4/52) = 1/26 or approximately 0.0385.
What is the probability of picking a black ace?
The probability of picking a black ace in one random draw from a normal pack of playing cards is 1/26.
What is the probability of a face card given that the card is black?
It is 3/13. The fact that the card is black makes no difference since the probability is the same for both colours.
Calculate the probability that an offspring will be black in the cross in punnet square b what is the probability it will be white?
In a monohybrid cross with black as dominant (B) and white as recessive (b), the probability of an offspring being black is 75% (3/4) and the probability of being white is 25% (1/4) according to the Punnett square ratios.
In a cross between two black guinea pigs what is the probability that an offspring will be black?
So I took the worksheet and found that in Punnett Square A (if you have the same worksheet) It has the pairs BB, Bb, Bb, and bb. B= black and b= white. The probablility of a black guinea pig is likely and white is unlikely since there is only 1 trait with 2 recessive alleles.
Which process is represented by the use of the Punnett square?
The Punnett square is used to predict the offspring genotypes resulting from a genetic cross between two individuals. It helps illustrate the possible combinations of alleles that can result from the combination of parental alleles during sexual reproduction.
What does a Punnett Square do for geneticists?
A Punnett Square is a tool used by geneticists to predict the outcomes of a genetic cross between two individuals. It helps determine the possible combinations of alleles that offspring can inherit from their parents and the likelihood of certain traits appearing in the next generation.
Suppose you have two mice one black one white the genotype for the black mouse is WW and the genotype for the white mouse is ww What would the punnet square look like?
In this case, when you cross a black mouse (WW) with a white mouse (ww), all offspring will be Ww, with a black coat. The Punnett square would show all offspring as Ww.
Why are Punnett squares useful in genetics?
You have a square the is split into fourths. 2 and 2 in bottom. It looks like a window. On top of the two top squares you put the alleles of the first parent. On the left you put the to alleles of the other parent. And you basically get one allele from each parent and put it in the square and it gives you the probably outcomes of the offspring.
What is the probability that one of the offspring mice will have black fur?
The answer depends on how big the litter is: as the litter size increases the probability of one black fur increases. But as it gets larger still, the probability falls because two or more black furs become more probable.
What is the probability that the black parent of a black offspring was homozygous for black coat?
Well you see black people are useless. Whoever made the black child is obviously an ape of some sort.
If a homozygous black guinea pig is crossed with a white guinea pig what is the probability that an offspring will have black fur?
depends if the black fur gene is dominant.. if it is... then yu would cross BB with bb making all heterozygous genotypes(Bb) therefore, having all possible offspring with black fur so theres a 100% probability of offspring with black fur(:
Show the cross between 2 heterozygous dogs. black fur B is dominant to brown fur b?
The Punnett square for crossing two heterozygous dogs (Bb x Bb) would result in a 25% chance of offspring with homozygous dominant black fur (BB), a 50% chance of offspring with heterozygous black fur (Bb), and a 25% chance of offspring with homozygous recessive brown fur (bb).
What is the probability of two black guinea pigs having black offspring?
depends on the two guinea pigs genotypes. could be anywhere from 75 to 100 percent.
Describe how to use the phenotype ratios to determine the percentage of offspring displaying each trait..a heterozygous gray bug Gg is crossed with a homozygous black bug gg?
To determine the percentage of offspring displaying each trait in the cross between a heterozygous gray bug (Gg) and a homozygous black bug (gg), first determine the possible genotypes of the offspring based on the parent genotypes (Gg x gg). The Punnett square will show the phenotypic ratios - 50% black (genotype gg) and 50% gray (genotype Gg). Thus, 50% of the offspring will display the black trait (gg) and 50% will display the gray trait (Gg).
